Michel Waisvisz "Yeti"

‘RECEIVER - radio telescope pointed ‘straight above’. During one year, hour-long ‘samples’ of space noise are taken twice per 24 hours (at 00:00 and 12:00 UTC) and transferred to the modulator. MODULATOR - consists of a multiplying system for these space noise samples, an assemblage of signal modulators, an input system for terrestrial sound signals and a time modulator which provides all these modulator systems with work instructions at the right moment. Roughly speaking, a signal is created in the modular in phases (initially, predominantly on the basis of the space noise received and gradually, in the course of a year, on the basis of a mixing of space noise and terrestrial and electronic sounds) which forms a message to be sent back into space with the help of a transmitter. TRANSMITTER - equipment with which the message is transmitted via a serial ‘straight above’. The power must be sufficient to send the message to the limits of our galaxy. LOCATION - public place not associated with technology or transport. Preferably next to or on a museum or on the square in front of a post office or in an open-air theatre.’ (Michel Waisvisz, 'Yeti. A design for an electro-mechanical communication object directed at space', De Appel, 5 (1985) 1, p. 18.)
